No error messages? Have you tried disconnecting/reconnecting the brake switch cable or the main connector to the motor?

I'm on my second dead controller. Initially Rad support said the replacement controller was not under warranty, it's less than 6 months old. I reported them to the BBB and within 48 hrs I got an email confirming they would cover replacement if it was proven to be at fault

The bike is okay, I'm loathe to put more money in to it. I have had lots of issues with the brakes and controller, numerous arguements with their support team and I've now reported them twice to the BBB.

I have it booked in for a service at a Rad store at the end of the month. I am probably going to give them another chance to fix it under warranty.

Is this the controller to which you refer and did you use the screen or the original Rad one?

Return it and get something better

I had my Rad City 5 controller die just before the warranty expired, it was replaced by a Rad store. The controller is dying 5 months later and Rad claim there is no warranty for the replacement product or the work they carried out!

What absolute bullshit. I have opened a BBB ticket and will never buy another product from this shower of shit

I opened a ticket on May 11, they got back to me on May 29th. They are also claiming that any service work and parts used are not covered by warranty!

That's what warranties are for

Had my Rad City 5 Plus delivered yesterday. I'm all charged up and the snow has melted enough for my first ride today
